В статье представлены результаты научных исследований по разработке рецептуры и технологии пудинга с использованием полуфабриката из цельносмолотого пророщенного зерна (ППЗ), в состав которого входят измельченные пророщенные зерна (пшеница - 14 %, рожь - 44 %, ячмень - 14 %, овес - 28 %) с размером частиц 200-400 мкм. Результаты исследования пищевой ценности ППЗ указывают на высокое содержание белка (12,4 %), пищевых волокон (11,7 %), жиров (2,9 %), витамина С (5,9 мг/100 г), энергетическая ценность составляет 321,1 ккал. Целью исследования является разработка рецептур и технологии пудинга с использованием полуфабриката из цельносмолотого пророщенного зерна вместо традиционных ванильных сухарей. Изучена возможность замены основного рецептурного компонента сухарей ванильных на ППЗ в рецептуре пудинга сухарного. Образец № 1 - пудинг с 25 %-ной заменой сухарей ванильных на ППЗ, образец № 2 - 50 %, образец № 3 - 75 %, образец № 4 - 100 %. В рецептуру пудинга из ППЗ был добавлен ванилин для формирования соответствующего вкуса. Установлено, что по органолептическим и физико-химическим показателям наиболее сбалансированным является образец с полной заменой ванильных сухарей на ППЗ. Кроме того, разработанный образец обладает меньшим содержанием жиров (на 16,7 %), по сравнению с контрольным образцом, уменьшилось содержание углеводов: моно- и дисахаридов (на 11,1 %), крахмала (на 9,3 %). Также увеличилось содержание пищевых волокон (на 457,1 %). Использование предложенного полуфабриката в технологии сладких блюд позволит не только расширить ассортимент, но и повысить пищевую и биологическую ценность изделия. The article presents the results of scientific research on the development of the formulation and technology of pudding using a semi-finished product from whole-ground sprouted grains (SPSG), which includes crushed sprouted grains (wheat - 14 %, rye - 44 %, barley - 14 %, oats - 28 %) with a particle size of 200-400 microns. The results of the study of the nutritional value of SPSG indicate a high content of protein (12.4 %), dietary fiber (11.7 %), fat (2.9 %), vitamin C (5.9 mg / 100 g), energy value is 321.1 kcal. The aim of the research is to develop recipes and technology for pudding using, instead of traditional vanilla rusks, a semi-finished product from whole-ground sprouted grains. The possibility of replacing the main recipe component of vanilla rusks with SPSG in the recipe for rusks pudding has been studied. Sample No. 1 - pudding with a 25 % replacement of vanilla rusks with SPSG; sample No. 2 - 50 %; sample No. 3 - 75 %; sample no. 4-100 %. Vanillin was added to the SPSG pudding formulation to create the appropriate flavor. It has been established that in terms of organoleptic and physicochemical indicators, the most balanced sample is with a complete replacement of vanilla rusks at the SPSG. In addition, the developed sample has a lower fat content (by 16.7 %) compared to the control sample, the content of carbohydrates decreased: mono- and disaccharides (by 11.1 %), starch (by 9.3 %). The content of dietary fiber also increased (by 457.1 %). The use of the proposed semi-finished product in the technology of sweet dishes will not only expand the range, but also increase the nutritional and biological value of the product.

Effects of different dietary fiber (DF) sources on short-chain fatty acids (SCFA) production and absorption in the hindgut of growing pigs were studied by an in vivo–vitro (ileal cannulated pigs and fecal inoculum-based fermentation) method. Thirty-six cannulated pigs (body weight: 48.5 ± 2.1 kg) were randomly allocated to 6 treatments containing the same DF content (16.5%), with either wheat bran (WB), corn bran (CB), sugar beet pulp (SBP), oat bran (OB), soybean hulls (SH), or rice bran (RB) as DF sources. Pigs were allowed 15 days for diet adaptation, and then, fresh ileal digesta and feces were collected to determine SCFA concentration which was normalized for food dry matter intake (DMI) and the hindgut DF fermentability. Fecal microbiota was inoculated into the freeze-dried ileal digesta samples to predict the ability of SCFA production and absorption in the hindgut by in vitro fermentation. The SH group had the largest concentration of total SCFA and propionate in ileal digesta and fecal samples of growing pigs (p < 0.05). Nonetheless, the predicted acetate, total SCFA production, absorption in the SBP group were the highest (p < 0.01), but the lowest in the OB group (p < 0.01) among all groups. Even SBP and OB group had a similar ratio of soluble DF (SDF) to insoluble DF (IDF). The CB group had high determined ileal and fecal butyrate concentration but the lowest butyrate production and absorption in the hindgut (p < 0.01). Overall, the source of DF had a great impact on the hindgut SCFA production and absorption, and SBP fiber had a great potential to increase hindgut SCFA production and absorption.

В последние годы все большее внимание уделяется разработке продукции, обогащенной растительными компонентами. Целью данной работы являлось исследование влияния смесей из порошков растительного происхождения на свойства теста и качество готовых изделий (булочной мелочи). В рецептуру изделий добавляли растительные смеси: № 1 - порошок облепихи, жимолости, мелкоплодных яблок и порошок из жмыха тыквы, № 2 - порошок облепихи и мелкоплодных яблок в количестве 10, 15 и 20 % от массы муки по сухому веществу. Смеси составляли из компонентов, взятых в равных количествах. Сравнительная оценка пищевой ценности смесей показала, что в смеси № 1 выше количество пищевых волокон, кальция и фосфора относительно смеси № 2. В смеси № 2 преобладает количество белков, жиров, органических кислот, калия, натрия, марганца и железа. По содержанию витаминов преимущество на стороне смеси № 2, за исключением витаминов В и В. Установили повышение кислотности теста с внесением растительных смесей, что указывает на интенсификацию процесса брожения. Исследование качества готовых изделий показало, что при соответствии физико-химических показателей требованиям технической документации, при дозировках смесей выше 10 % отмечали значительное потемнение цвета изделий, появление растительного привкуса, а в изделиях с добавлением смеси №1 неприятное послевкусие. Наиболее рациональной для производства хлебобулочных изделий повышенной пищевой ценности для здорового питания признана рецептура с использованием растительной смеси № 2 из порошков облепихи и мелкоплодных яблок в количестве 10 % к массе муки. In recent years, more and more attention has been paid to the development of products enriched with plant components. The purpose of this work was to study the effect of mixtures of powders of vegetable origin on the properties of dough and the quality of finished products (bakery trifles). Vegetable mixtures were added to the recipe of the products: No. 1 - sea buckthorn powder, honeysuckle, small-fruited apples and pumpkin cake powder; No. 2 - sea buckthorn powder and small-fruited apples, in the amount of 10, 15 and 20 % of the flour weight by dry matter. The mixtures were made up of components taken in equal quantities. A comparative assessment of the nutritional value of the mixtures showed that the amount of dietary fiber, calcium and phosphorus in mixture No. 1 is higher, relative to mixture No. 2. The mixture No. 2 is dominated by the amount of proteins, fats, organic acids, potassium, sodium, manganese and iron. In terms of vitamin content, the advantage is on the side of mixture No. 2, with the exception of vitamins B and B. An increase in the acidity of the dough was established, with the introduction of vegetable mixtures, which indicates an intensification of the fermentation process. The study of the quality of finished products showed that when the physico-chemical parameters meet the requirements of technical documentation, at dosages of mixtures above 10%, a significant darkening of the color of the products, the appearance of a vegetable taste, and in products with the addition of mixture No. 1, an unpleasant aftertaste was noted. The most rational recipe for the production of bakery products of increased nutritional value for a healthy diet is recognized, using a vegetable mixture No. 2 of sea buckthorn powders and small-fruited apples in an amount of 10 % by weight of flour.

Chestnut-added milk (CM) was produced with 2 different methods. In the first method, chestnuts were roasted, and in the second method, they were cooked in bain-marie and then added to milk at different ratios (5, 15, 25 %). The addition of chestnuts to milk statistically increased the amount of protein, dietary fiber, carbohydrate, energy, mineral (Ca, K, P, Mg), antioxidant capacity and total phenolic content compared to the control, whereas it did not cause a significant change in sensory properties. Therefore, the chestnut is a suitable supplementation for milk.

One of the most prominent concerns that has arisen from global events such as the Coronavirus Disease 2019 (COVID-19) pandemic is how the immune system might be enhanced to provide greater protection against malignant conditions and diseases. Dietary modification is one of the major fields of research, with special focus on how diet interacts with immunity through impacts on factors such as the gut microbiome, inflammation, and nutritional imbalance. This review focuses on current research regarding the use of bioactives derived from berries as a dietary supplement to improve immunity, with discussions of relevant clinical studies. Major bioactive, metabolic compounds of focus- flavonoids, anthocyanins, alkaloids, dietary fiber, and stilbenes- have demonstrated biochemical merits in modulating immunity. In addition, blueberries, goji berries, black raspberries, and cranberries, which have been extensively researched and recently gained interest for their effects on the immune system in animal and cell models, may also hold promise in providing similar benefits to humans, though the precise immunological effects have yet to be clearly determined. Overall, the field of berry research as it relates to diet and immunity shows potential, but more clinical studies will be necessary for a full understanding of the mechanisms of berry immunomodulation.

Strawberry tree (Arbutus Unedo L.) is one of the evergreen trees that grow spontaneously in Moroccan forests. This tall shrub is traditionally used in grazing zones of some Moroccan areas, especially during the dry season, but its value in Morocco has still been underestimated. In this paper, the nutritional composition of A. unedo leaves sample collected from seven Moroccan regions has been assessed. For this, the leaves were dried, crushed, and chemically analyzed for their proximate composition, energetic value, total and reducing sugar, and mineral composition. Results of this study suggested that samples from BniAarouse (BA) region showed the highest contents of essential nutrients such as proteins, dietary fiber, ashes, and fat with average values of 7.53, 17.89, 4.14, and 8.05 g/ 100 g of dry weight, respectively, which positively influences its consumption by small ruminants. Cluster analysis based on surveyed parameters separated the strawberries individuals into four distinct groups, providing a high variability among and within studied locations. That could be related to the diversity of the edaphoclimatic conditions between regions and to the genetic effect. The results of the present study highlighted the potential use of leaves as livestock feed, with intermediate quality, and promotes their optimal cultivation and subsequent domestication in Morocco.

The evidenced relevance of dietary fibers (DF) as functional ingredients shifted the research focus towards their incorporation into gluten-free (GF) bread, aiming to attain the DF contents required for the manifestation of health benefits. Numerous studies addressing the inclusion of DF from diverse sources rendered useful information regarding the role of DF in GF batter’s rheological properties, as well as the end product’s technological and nutritional qualities. The presented comprehensive review aspires to provide insight into the changes in fiber-enriched GF batter’s fundamental rheological properties, and technological, sensory, and nutritional GF bread quality from the insoluble and soluble DF (IDF and SDF) perspective. Different mechanisms for understanding IDF and SDF action on GF batter and bread were discussed. In general, IDF and SDF can enhance, but also diminish, the properties of GF batter and bread, depending on their addition level and the presence of available water in the GF system. However, it was seen that SDF addition provides a more homogenous GF batter structure, leading to bread with higher volumes and softer crumb, compared to IDF. The sensory properties of fiber-enriched GF breads were acceptable in most cases when the inclusion level was up to 7 g/100 g, regardless of the fiber type, enabling the labeling of the bread as a source of fiber.

Purpose. Determine the formation of physico-chemical quality indicators (berry weight, protein, carbohydrates, fat, dietary fiber, organic acids) of fresh, dried and frozen sea buckthorn fruits of different varieties. Methods. Laboratory, mathematical and statistical, physicochemical. Results. The water content in sea buckthorn berries was the highest, but also varied significantly depending on the variety. The varieties of sea buckthorn ‘Haleryt’ and ‘Yelyzaveta’ had the highest content – 90%, by 2 and 3% less in the varieties ‘Burshtynove namysto’ and ‘Altaiska’, in the varieties ‘Sonechko’ and ‘Uliublena’ – 85%. The lowest water content was in the berries of ‘Ryzhyk’, ‘Podruha’, ‘Diuimovochka’, ‘Chechek’ varieties – 75–78%. Dried fruits contained water from 22 to 16%. In the varieties ‘Uliublena’, ‘Yelyzaveta’, ‘Altaiska’ – 22%, ‘Haleryt’, ‘Diuimovochka’, ‘Sonechko’, ‘Burshtynove Namysto’ – 20%, ‘Avhustyna’, ‘Ryzhyk’, ‘Podruha’ – 18%, ‘Veleten’ and ‘Chechek’ – 17 and 16%, respectively. The content of dietary fiber was 4.5–6.2% depending on the variety. The lowest content of dietary fiber was found in the varieties ‘Uliublena’ and ‘Altaiska’ – 4.5–4.7% in fresh and 2.4–2.5% in dried berries. The highest rates were in the varieties ‘Avhustyna’, ‘Sonechko’, ‘Burshtynove Namysto’ in fresh varieties – 6.0, 6.2 and 5.9%, and in dried varieties – 5.5%. The ‘Chechek’ and ‘Veleten’ varieties contained 5.7% in fresh berries and 5.0 and 4.5% in dried berries. The content of fat in fresh berries was in the range of 5.0–5.7%, depending on the variety. In dried berries it increased to 6.0–6.7% or 18–20% depending on the variety of sea buckthorn. In fast-freezing berries, this figure decreased to 4.5–5.2% or 9–10%. The content of organic acids in fresh fruits was the highest – 1.5–2.0%, depending on the sea buckthorn variety. Their content in dried berries decreased to 1.3–1.7% except for the varieties ‘Avhustyna’, ‘Sonechko’ and ‘Burshtynove namysto’, and in the frozen ones to 0.3–0.9%. It should be noted that a similar trend is observed in frozen berries of ‘Avhustyna’, ‘Sonechko’ and ‘Burshtynove namysto’ varieties. Conclusions. It is established that physicochemical quality indicators of fresh, dried and frozen sea buckthorn berries vary depending on the variety. The varieties ‘Avhustyna’, ‘Sonechko’, ‘Burshtynove Namysto’ have the largest weight of one berry 1.4–1.5 g. 8–6.0%), fat (5.5–5.7%), protein (1.5%), organic acids (2.0%) and dietary fiber (5.9–6.2%) in fresh berries.
